Intel Express 530T Switch Users Guide
I keep getting an intermittent loss of link. (or data is not
being transmitted) Why?
• You may be using the wrong grade of cable. The wrong cable can
cause erratic performance and you may eventually lose the connec-
tion between the port and the attached device.
• Check the duplex setting for the device connected to the port. You
may have to use the Local Management or Web Device Manager
to force the port to half or full duplex.
• A cable segment somewhere in your collision domain may be too
long. Make sure none of your UTP cabling is longer than 100
meters.
• Check the Ethernet cable pairs. The TX pairs (pins 1 and 2) and
the RX pairs (pins 3 and 6) should be twisted pairs. See diagram in
Chapter 1.
I created a tag-based VLAN, and I have tag-capable LAN
adapters in my PCs, but I can still communicate with
devices outside the VLAN. Why?
Check to make sure that you have assigned a VID to the PC. If you
don't assign a VID to the NIC in the PC it will behave as an untagged
device. The default VID for untagged devices=1 so all untagged PCs
will be a member of the DEFAULT_VLAN.
Can I stack 510, 520, or 550 switches with the 530T?
No. The only switch that can be stacked with the 530T is the 535T.
You can stack up to three 535T switches with a 530T.

Locating MIB files

If you use a MIB browser, you can configure or view statistics for the
switch. You can find these switch MIB files at the Intel Customer
Support Web site at http://support.intel.com/support/express/switches.
• intel.mib
• int_gen.mib
• int_2530.mib
When compiling the MIBs into an SNMP-compliant management
application, compile the intel.mib first then compile the int_gen.mib,
int_s530.mib, int_pbrd.mib, and int_qprb.mib files.
• int_pbrd.mib
• int_qprd.mib
